I am getting this error in Hive queries.CM shows hive service is up and running just fine without any exits. Recently had connected to Hive through Tableau as well. Usually happens around the same time in morning,
How do I fix this? What could be the issue? No heavy processing on server when this happens. very few and small queries running at the time it happens.
